In Washington DC, I'm seeing periodic pixellation like breakups on my
various Comcast HD channels. My cable box is the Motorola DCT 6208
(with built-in DVR).

After watching this carefully for a while, it definitely seems to me
that the breakups correlate to dramatic light to dark or dark to light
transitions in the image.

I recently moved, about a mile within Washington DC, and I saw exactly
the same behavior at my previous location.

I'm going to call Comcast to have a technician check my signal strength,
but first I have a few questions:

* Does the Motorola DCT 6208 cable box keep track of this? Ie. is
there some internal counter that shows "loss of synch" on the hi-def
MPEG-2 datastream?

* Can Comcast headquarters automatically query boxes to figure out if
large scale problems are occurring.

Thanks

No the box does not keep track of this but your cable company has tools to
check your signals from there end and onsite..

The company should know if its a large scale problem due to user
feedback.......

If its happening at a new location most likely the box needs to
bereplaced..... I troubleshoot these Dct's and Internet all day long on the
job specifically the 6208. It could also mean you need a booster added to
your cable line to boost the sig.....

I would call your local cable company and they will most likely send a
techout just incase if its not the box...
